MoneySavingExpert.com has urged Asda and Lidl shoppers to claim the free cash – but they need to act fast.

How to get a £5 Lidl voucher

From today (Wednesday), Lidl is offering one million £5 off vouchers via its app to spend by next Tuesday (28 February).

To get the Lidl voucher you need to download the Lidl Plus app on either iOS or Android, and signup. Click the ‘More’ tab at the bottom of the app and tap ‘Redeem code’. Enter the code ‘FEELGOOD’ and the voucher appear in the ‘Coupons’ section of the app.

You’ll need to activate the voucher in the ‘Coupons’ section of the app before scanning your Lidl Plus app at the till. The cashier will need to see the coupon in the app – not a screenshot or printout.

There are one million vouchers available, and you’ll have from today until Tuesday 28 February to both claim and spend the voucher, which must be done in a single transaction. You’ll need to spend £25 to use the voucher, after any other discounts are taken into account. You can’t use the voucher for alcohol, infant formula or gift cards.

How to get £5 off at Asda

You need to be a new member of Asda Rewards to get the £5 discount and complete your first shop – although there’s no minimum value for this.

To get the voucher, you need to download the Asda Rewards app and signup. You’ll then see various offers under the ‘Earn’ tab, which Asda calls ‘Missions’. This one is called ‘First Scan Bonus’. You need to complete your first shop at Asda and scan the app and the £5 bonus will then appear in your Cashpot automatically.

To spend the money, you need to convert your Cashpot balance into vouchers to spend, which you can do within the app in increments of £1. You’ll then need to scan the voucher in the app when you go through the checkout in-store. If you shop online the voucher will automatically be applied to your shop.

You can’t use the Asda voucher on kiosk items, petrol, pharmacy, gift cards or infant formula.

Aldi voucher warning

If you’ve seen an offer for 40% off at Aldi and think it might be too good to be true, you’re right.

Aldi have warned customers about the hoax on its Facebook page, saying that it’s fraudulent and the voucher cannot be redeemed in its stores.

It also warned customers not to enter their personal details on the hoax post.
